IMHO, both versions are OK. There's nothing technically "wrong" with either, so it's difficult to say one is "better" than the other without knowing the subject's goals, your intent and/or the use to which the image will be put, the directions from the art director of a hypothetical ad campaign, etc..
I've seen images processed much like the left version enlarged to be 6 foot high displayed prominently in trendy stores. At the opposite end of the spectrum, I would bet the the mother of the subject would absolutely hate the LH version, tolerate the RH version a bit more, but in their heart, prefer if the shot was lit completely differently, ie, much less starkly.
In fact, these are hardly the only two choices -- starting with the LH image, there are an infinite number of technically OK choices now open to us at the push of a button. These range from gritty, inner city cross processed looks to "Portrait Professional" looks.
If I had absolutely nothing else to go on, and forced to express my preferences, I would probably go for something in-between the two versions you posted. This would at least give the guy a skin color that's neither as sallow as the LH version, and not as orange as the RH version.
